Story completion. Play through to the summit and let the ending carry you back to the start - the achievement fires on your return, not at the summit itself, so do not quit during the credits. Unmissable.
The underground passage is the dark section patrolled by the large flying guardians (the 'war machines'). Your scarf tears when a guardian catches you, so the goal is to get through the whole passage - community guides include the downhill slide at the end - without ever being hit. Move between cover, watch the guardians' search lights and wait for them to turn away before crossing open ground. If you get caught, restart the level from the menu rather than finishing it, then try again. Chapter select (available after your first completion) lets you jump straight here.
Clock-gated: start a journey, then do not play for at least a week, then start again. It cannot be rushed in a normal way, so begin the clock early - finish your other achievements, then leave the game alone for seven days and come back to collect this one.
Needs online play. You must reach the summit together with another player and then return to the beginning. Stay close to your companion through the final snowy climb and the summit - companions are matched automatically, so if yours drops out you may need another attempt. Combines naturally with Companion.
Needs online play. Pair up with one stranger and stay with them for most of a full journey, then finish and return to the beginning. Community guides report that starting from chapter select partway through can still count, as long as you stay with the same partner for the majority of what remains, but the safest route is a full run. Chirp often so you do not lose each other. Crossing will usually unlock on the same run.
A hidden flower in the open desert dunes section. Community guides place it in a small depression in the sands of that area, and you have to shout (sing) near it to make it bloom and earn the achievement. Exact spot not verified by us - follow a community guide or video if you cannot find it.
Free all the cloth creatures in the desert dunes section - community guides describe five groups to find before heading into the structure at the end of the area. Explore the dunes thoroughly and shout near each trapped cloth creature to release it. Chapter select lets you replay the desert if you miss one.
Needs online play. You must meet ten or more different travelers. Most journeys only pair you with a few people, so this usually unlocks over several playthroughs - it will come naturally if you are replaying for the other online achievements and glyphs.
Needs online play. When you are next to your companion, sit down and stay seated alongside them for over 20 seconds. Many players will copy you if you sit first - a chirp to get their attention helps.
In the temple level near the end of the journey (the large tower you climb). Community guides describe a hidden creature in one of the openings of the tower partway up; you have to shout near it to earn the achievement. Exact spot not verified by us - use a community guide or video if needed. Chapter select makes a retry quick.
Collect every glowing scarf symbol in the game. Progress carries across journeys, so you do not need to find them all in one run. Several are off the obvious path, and community guides note that some in the sliding sections require you to steer off-line during the slide to reach them. Use a collectible map and tick them off level by level with chapter select. Pairs well with History.
In the first broken-bridge area early in the game, you normally collect cloth to rebuild the whole bridge. For this achievement you rebuild only part of it and use your scarf's flight to cross the gap yourself. Community guides describe leaving one end unrepaired and using the floating cloth to lift yourself up onto the remaining broken section before gliding across. Easy to retry with chapter select.
Find all ten hidden glyphs (the stone markers that show you a scene from the story). They are spread across the levels, so use chapter select and a glyph map to sweep each level. Pairs well with Transcendence.
During the long downhill sand slide through the sunken city, steer through at least 15 of the gates you pass. Steer early rather than late - you can slow yourself slightly by holding back on the stick. If you miss too many, restart the chapter and try again.
